I've crashed a couple of times in the past 2 years - once against the corner of a parked car bumper (no joikes about dogs chasing cars please) and once off a large pothole. My front wheel remains true, but I've recently broken a spoke and am considering a new wheelset (money burning a hole in my pocket I suppose). My bike is an aluminum Scattante (old Super Go stores) with Shimano Ultegra 9 speed, 3 years old, Weyless wheelset. Does anyone have an opinion on when to start looking at replacing wheels and also anyone's experience with Shimano R550 / 560 or Bontrager race.

Thanks in advance, Rob
